Journal ArticleDOI
A Plant miRNA Contributes to Antibacterial Resistance by Repressing Auxin Signaling
Lionel Navarro,Patrice Dunoyer,Florence Jay,Benedict Arnold,Nihal Dharmasiri,Mark Estelle,Olivier Voinnet,Jonathan D. G. Jones +7 more
TL;DR: It is shown that a flagellin-derived peptide induces a plant microRNA (miRNA) that negatively regulates messenger RNAs for the F-box auxin receptors TIR1, AFB2, and AFB3, implicating auxin in disease susceptibility and miRNA-mediated suppression of auxin signaling in resistance.
Journal ArticleDOI
Dynamics and biological relevance of DNA demethylation in Arabidopsis antibacterial defense
Agnès Yu,Gersende Lepère,Florence Jay,Jingyu Wang,Laure Bapaume,Yu Wang,Anne-Laure Abraham,Jon Penterman,Robert L. Fischer,Olivier Voinnet,Lionel Navarro +10 more
TL;DR: Evidence is provided that DNA demethylation is part of a plant-induced immune response, potentially acting to prime transcriptional activation of some defense genes linked to TEs/repeats.
Journal ArticleDOI
Suppression of the MicroRNA Pathway by Bacterial Effector Proteins
TL;DR: Bacteria have evolved to suppress RNA silencing to cause disease, and miRNA-deficient mutants of Arabidopsis partly restore growth of a type III secretion-defective mutant of Pseudomonas syringae are identified.
Journal ArticleDOI
Selective autophagy degrades DICER and AGO2 and regulates miRNA activity
Derrick Gibbings,Serge Mostowy,Florence Jay,Yannick Schwab,Pascale Cossart,Pascale Cossart,Pascale Cossart,Olivier Voinnet +7 more
TL;DR: It is shown that the DICER enzyme and the main miRNA effector, AGO2, are targeted for degradation as miRNA-free entities by the selective autophagy receptor NDP52, underscoring the importance of fine-tuned regulation of the miRNA pathway.
Journal ArticleDOI
An endogenous, systemic RNAi pathway in plants.
Patrice Dunoyer,Christopher A. Brosnan,Gregory Schott,Yu Wang,Florence Jay,Abdelmalek Alioua,Christophe Himber,Olivier Voinnet +7 more
TL;DR: In this paper, an exhaustive analysis performed using Arabidopsis was conducted to find the existence of a bona fide, endogenous and systemic RNA-silencing pathway in plants that may have implications in adaptation, epiallelism and trans-generational memory.
